How to capture a log with adb logcat
Usually a full sync log is sufficient to find out what's wrong when the synchronisation fails. However, in some cases a full *system* log is necessary to track down the original cause. If the device is rooted "CatLog" is the weapon of choice. If it's not we need to resort to a tool called 'adb logcat'.
Note that you need to have a Linux machine or Mac for this.
1.) Download or install the Android-SDK (http://developer.android.com/sdk/index.html#Other). If you're using Ubuntu you can also run "sudo apt-get install android-tools-adb".
3.) Connect your smartphone via USB to your machine
4.) Run "adb logcat > logfile" in the commandline. Note: this overwrites "logfile" if it already exists.
5.) Reproduce the original issue e.g. by starting a synchronisation on your smartphone.
6.) Afterwards kill adb by pressing the combination "Ctrl + c" in the commandline window.
7.) Forward the file "logfile" to us.
